This invent-ion krelates to window Vframes and sashes, and particularly to double hung windows in which twosashes are individually'slidable between upright frame members.

Such structures `should include weather proofing devices to prevent the ,entranceof rain and wind, heator cold, and also provide means for ventilation when required.

It is furthermore desirable that either sash may be readily raised or lowered, freely and smoothly,` without` binding or appreciable` wear of the parts in frictional contact.

It is also regarded as advantageous to arrange the sashes in such manner as to permit them yto swing upon pivots yinto various angularly inclined positions within the room, whereby both sides may be presented lfor cleaning or similar purposes, avoiding the hazards and inconvenience usually encountered in such operations, `the sash being spring-locked in whatever position it is caused to assume, assuring the most complete ventilation.

.Another aim is in the production of a device readily applied to any Common type of window, without mutilating the c frame, whereby the sashes may be pivoted, the ldevice being inexpensive and easily applied.

These advantageous objects are attained by the novel construction and arrangement of few and simple parts hereinafter described i and shownin the annexed drawings, forming an essential part of this disclosure, ,andV in which Figure lis a perspective view showing a conventional type of window frame and-sash, illustrating an application of the invention, the sashes being shown in an extre'meextended position.

, In thek drawings the numeral'llO designates the sill of a conventionalwindow, having upright frame members-11connected by a lintel 112 at the top.

The frame, shown ingreater detailin Figure 2, includes inner and Aouter casings 14 f and 15 respectively, joined at their inner .-Engagedat the front edge ofthe casing plate 14 isa guide moulding'18,`while at the opposite outer side'is a similar element 19, a

:edges by'a stile 16, vthe space ratthe rear of 65 .which isutilized by sash counterweights 17.

and outer, are composed of theA usual `frame work, in which are vset panes of glass 23, and

it is to be noted for reasons further on apparent, that the outer sash 22 is of. slightly lesser ,width than the inner orfront sash 21.

*Betweeni the parting strip 20 and mouldings18 and 19 are open spaces'in which the sashes of ordinary windows normally slide. y

In thev present improvement, the sashes are reduced-in width ,to rclear the moulding and strips, and metallicy plates 25 are fixed directly to the lstile y16 within the mentioned spaces ordinarily guiding the sashes. f

These yplates 25 extend the full length of the window stile from the sill 10to the lintel .12, and integral with theplates 25 are flanges 50 Figure 6 isa rear elevational; view thereof. Ametal block 34 is provided with angularly grooved side edges adapted to engage and freely move on the angular guides 28 and 29, the block being recessed, as at 35, on its outer sides to receive a metal plate 36, through which passes a pivot screw 37 also passing through the lower portion of the block 34, and rigidly set in the lower member of the window sash 2l so that the sash pivots on the body of the screw.

Between the block y34 and side element of the window sash is a metal plate 38 attached to the sash edge by screws 39 passing thnough openings 39, the plate extending coincident with the full height of the sash.

A portion of the plate 38 is pressed inwardly formingan oliset 40 seating within a corresponding recess in the side of the sash frame, this plate being cut away at its upper end, as at 41, to receive a stud 42, clamped by the arms of a double armed spring detent 43, when the sash is in an upright position, the detentbeing secured by a headed pin 54.

Adjacent, but free of the plate 38, at its odset portion 40, is a hat link 44 connected to the plate by a pivotal rivet 45 near its lower end, while in its upper end is set a'stud 46 pivotally connecting another block 48.

The block 48 is grooved at its side edges to slide on the angle guides 28 and 29, and has undercut, opposed recesses 49 to slidably receive the plate 36, the upper of which presents a transverse friction bar 50, its ends impinging against Vthe plate 25 and entering the spaces immediately within the elements 26 and 27, the stud 4'2 being rigidly secured in the plate 49. A continuation of the plate 36 has an opening 54 in which is secured the end of a chain running over a pulley and provided with a weight counterbalancing the sash as is usual.

Formed in the lower portion of the plate 36 are a series of spaced perforations 5l engageable by a spring detent 52, the shank of which is held by a nut 53 to the lstud 46 set in the block 48.

From the foregoing it will be seen that when the sashes are turned angularly, the plate 38--40 is moved with the sash, actuating the link 44 and causing the Vdetent 52 to engage one or :another of the openings 51 with snllicient tension to hold the window sash in its adjusted position.

When the sashes are closed the knob 42 is encircled by the spring 43, an opening being formed in the sash frame to accommodate this knob.

From the foregoing it will be apparent that la very simple device has been disclosed, its parts being entirely of metal, light in weight and readily formed by `ordinary die processes; the arrangement is such as to positivelyprevent the entrance of wind or rain to the interior and that all wearing surfaces are of ample size to resist wear indefinitely.

While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claims.
